Aquatic Effects Monitoring Program (AEMP) Appendix A, Evaluation of Effects Monitoring Report, Ekati Diamond Mine (BHP Billiton, July 2007)
1 July 2007Report
The 2006 Aquatic Effects Monitoring Program (AEMP) evaluated potential impacts of the Ekati Diamond Mine on aquatic ecosystems in the Koala and King-Cujo watersheds, detecting measurable effects on water quality, phytoplankton, zooplankton, and benthic communities attributable to discharge from the Long Lake Containment Facility and King Pond Settling Facility, though no significant environmental impacts were identified. All discharged water remained within compliance limits and below most Canadian Council of Ministers of Environment (CCME) guidelines for freshwater aquatic life protection.

Aquatic Effects Monitoring Program (AEMP) Introduction (Independent Environmental Monitoring Agency, March 2005)
17 March 2005Presentation
This workshop presentation outlines Ekati's Aquatic Effects Monitoring Program (AEMP) for 2004, detailing surveillance of water quality, fish, and aquatic organisms across the Koala and King-Cujo watersheds. Key findings show that all releases met water licence compliance and CCME guidelines, though some water quality parameters increased downstream and cladocera populations in Moose Lake showed continued decline with minor recovery trends.

Ammonium Nitrate (AN) and Kodiak Lake Study, Ekati Diamond Mine (BHP Billiton, March 2005)
1 March 2005Report
This 2004 environmental assessment examines whether ammonium nitrate storage facility operations and surface runoff were affecting Kodiak Lake at the Ekati Diamond Mine. The study documents that remediation efforts since 2002 have successfully reduced nitrogen compound concentrations entering the lake, with measurable but small localized effects constrained to two small bays receiving surface flow, showing elevated phytoplankton biomass but no adverse impacts on zooplankton or water quality parameters.

Aquatic Effects Monitoring Program (AEMP) Appendix A, Evaluation of Effects Data Report, Draft for Public Review, Ekati Diamond Mine (BHP Billiton, February 2005)
1 February 2005Report
This is the 2004 Aquatic Effects Monitoring Program (AEMP) evaluation report for the Ekati Diamond Mine, assessing changes in aquatic ecosystems in the Koala and King-Cujo watersheds and their downstream areas (Lac de Gras and Lac du Sauvage). The report presents detailed monitoring of water quality, physical limnology, and biological communities, finding that while some water quality parameters showed measurable changes due to facility discharges (LLCF and KPSF), all values remained below Canadian guidelines and minimal biological effects were detected in downstream waterbodies.

Independent Third-Party Review of the Aquatic Effects Monitoring Program (AEMP) (Zajdlik & Associates, 2005)
~2005Report
Approximate date — inferred from filename
Independent 3rd-party review of the Ekati Diamond Mine's Aquatic Effects Monitoring Program (AEMP) conducted by Zajdlik & Associates for 2002 monitoring data, evaluating statistical treatment of nitrate, copper, and zooplankton measurements to assess environmental changes downstream of the Low-Level Containment Facility. The review identifies strengths in BHPB's comprehensive monitoring program while recommending improvements in data handling procedures, alternative statistical approaches, and use of gradient and multivariate analyses.

Panda Diversion Channel Monitoring Program, Volume I, Technical Report, Draft for Public Review, Ekati Diamond Mine (BHP Billiton, December 2004)
1 December 2004Report
This technical report documents the sixth year (2004) of monitoring the Panda Diversion Channel (PDC) at Ekati Diamond Mine to assess its effectiveness as compensatory fish habitat. The program measured physical parameters (flows, temperatures, habitat), biological communities (periphyton, benthic invertebrates), and fish populations, particularly Arctic grayling spawning, rearing, and outmigration, comparing results with reference streams Pigeon and Polar-Vulture.

Grizzly Lake Aquatic Assessment, Ekati Diamond Mine (BHP Billiton, January 2004)
15 January 2004Report
This 2003 aquatic assessment of Grizzly Lake at the Ekati Diamond Mine examines water quality, limnology, and biological communities to determine nutrient sources and effects of changing water chemistry on aquatic life. Results show elevated copper and nitrate concentrations historically, though nitrate decreased in 2002-2003, while aquatic biota remained relatively unaffected and typical of other Ekati area lakes.

Data Report on Water Quality, Phytoplankton and Zooplankton of the Long Lake Containment Facility, Ekati Diamond Mine (BHP Billiton, January 2004)
1 January 2004Report
This report presents water quality, phytoplankton, and zooplankton monitoring data collected from Cells C, D, and E of the Long Lake Containment Facility at the Ekati Diamond Mine during July-September 2003, in support of a risk assessment for discharging Fox Pit mine water. The study found significant horizontal gradients in water quality between cells, with stratification in Cells D and E, and documented the effectiveness of filter dykes and dilution processes in reducing suspended solids and contaminant concentrations.

Panda Diversion Channel Monitoring Program, Draft, Ekati Diamond Mine (BHP Billiton, December 2003)
1 December 2003Report
This report documents the sixth year (2003) of monitoring fish populations in the Panda Diversion Channel (PDC), a man-made compensatory stream constructed in 1998 at the Ekati Diamond Mine. The study measured the productivity of the PDC relative to two reference streams (Pigeon and Polar-Vulture) by monitoring Arctic grayling spawning success, fry emergence, growth rates, survival, and outmigration, revealing that while the PDC supports high spawner densities, fry survival and growth rates were lower than reference streams due to incomplete ecosystem seasoning and density-dependent effects.
